Paris hosted its 16th annual “Nuit Blanche” (sleepless) contemporary art festival overnight to Sunday, drawing a crowd of about a million visitors to the 150 art installations that had been put on display across the city.

Between sundown and sunrise, Parisians were treated to a spectacular contemporary art show, including a ballet in the Forum des Halles shopping centre, a zombie skeleton installation and the opportunity to express themselves with giant 3D letters by the river Seine.

The art collective Invisible Playground Network wanted visitors to participate in their art installation, letting them be the creators by composing phrases and messages with the help of giant letters placed by the Seine river. In the photo in the tweet below, someone has made a play on words, writing : "A Seine of love".
